NP_TypePadAntiSpam

NP_TypePadAntiSpam is a plugin that integrates TypePad AntiSpam with Nucleus CMS. TypePad AntiSpam is an Akismet-compatible collaborative spam blocking service from Six Apart.

NP_TypePadAntiSpam は、Nucleus CMS で TypePad AntiSpam を利用できるようにするプラグインです。TypePad AntiSpam は、シックス・アパート社が提供する Akismet 互換の協調スパムフィルターサービスです。

Prototype

This version is a prototype, a quick hack based on NP_Akismet and NP_AddSpamCheckEvent, just to see if the API works with Nucleus. However, it practically works and rejects comment spams in English pretty well. Install this in your plugin directory, and set your API Key in admin area.
